Usage

kubectl datree test [datree CLI args] -- [options]

Arguments:

datree CLI args:
  This plugin supports all of the Datree CLI arguments: https://hub.datree.io/cli-arguments

options:
  [-n <namespace>] Test all resources in the cluster belonging to the specified namespace
  [--all] Test all resources in the cluster
      When using '--all', you can specify namespaces to exclude using '--exclude <namespace> --exclude <namespace2>'
  [<resource type> <resource name> <namespace>] Test a single resource in the cluster

  Running 'kubectl datree test' with no arguments is equivalent to 'kubectl datree test -- -n default'

Specification

The plugin supports the following resource types:

• Pod
• Service
• Ingress
• Daemonset
• Deployment
• Replicaset
• Statefulset
• Job
• CronJob
• CRD (not the custom resource itself, but its definition)

:warning: When running against a given namespace, only resources of these types will be checked.

Examples

The following command will fetch all resources within the namespace exmpl, and execute a policy check against them:

kubectl datree test -- -n exmpl

The following command will fetch the resource of kind Service named myAwesomeService in namespace mySweetNamespace, and execute a policy check against it using k8s schema version 1.22.0:

kubectl datree test -s "1.22.0" -- service myAwesomeService mySweetNamespace

The following command will fetch all resources from all namespaces in the cluster except for 'default':

kubectl datree test -- --all --exclude default

Example test with no misconfigurations:
